After a May 15 meeting with Syrian opposition leaders, Secretary of State John Kerry said he has personally seen “raw data” which indicates the Syrian government “has used chlorine gas as a chemical weapon… in recent months.”

He said this has happened in a “number of instances” but does not want to provide specifics and thus lock the U.S. “down [on] a precise date, time, [or] manner of action.”

Kerry added, “I’m not going to discuss to what specific weapons or what country may… be providing or not providing [the arms]. I will say that out of today’s meeting, every facet of what can be done is going to be ramped up. Every facet.”
